Cuisine & Edibility
Clownfish
Not consumed — iconic ornamental marine species famous for its symbiotic relationship with sea anemones; a staple of reef aquariums worldwide.
European Sturgeon
Critically Endangered — consumption is illegal throughout its range. Historically prized for its delicate flesh and black caviar; now one of the world's most threatened fish species.
Species Overview
Clownfish
The ocellaris clownfish is a protandrous sequential hermaphrodite that lives in a mutualistic relationship with sea anemones. Its mucus coating protects it from anemone stings. All individuals are born male and the dominant fish transitions to female.
European Sturgeon
The European sturgeon is a critically endangered anadromous fish that can live over 100 years. Once abundant in European rivers, it is now restricted to a small population in the Gironde estuary. Its eggs are harvested as beluga-grade caviar.
